We adopts famous domesticlarge steel enterprises(such as Anshan
lron and Steel Group corporation and Hengyang Steel Group)
production of material to produce drill pipe, and heat treatment of
materials by using an integrated multi-processing furnace,
professional CNC machining was applied in all of the connection
thread processing, all the threads are configured thread gauge,
which are in accordance with international standard, lnternal
thickening technology has carried on the tempering process after
friction welding, so the processing quality of drill pipe is
stable, reliable, use cycle greatly extended.

We can process different length, diameter and wall thickness and
material of APl standard thread rod, we also can design and
manufacture drill pipe according to customers' requirement ofthe
material, length, wall thickness and connection thread.

Applications

Widely used in mines, quarries, earthworks and other engineering
drilling blasting hole, guardrail hole, mountain reinforcement,
anchorage and other engineering holes, geothermal exploration hole,
Well bore and other fields.
